Retarded Polarization Phenomena in BaTiO3 Crystals

Abstract

Slow polarization phenomena in BaTiO₃ c‐domain crystals were observed for applied electric fields smaller than 1 kv/cm. It is shown that the rate of change of polarization with time for small but constant fields implies the same phenomena observed for switching experiments performed at fields considerably larger than 1 kv/cm. No threshold field was found below which antiparallel nuclei would not propagate and complete the polarization reversal cycle.
